Issue with moving to a namespace

Hey there,
when i try to move a project to another namespace i get an error 500 with this error:

Completed 500 Internal Server Error in 504ms (ActiveRecord: 70.5ms | Elasticsearch: 0.0ms | Allocations: 47181)

OpenSSL::Cipher::CipherError ():

Same is when i want to view my runners. The error there is:

Processing by Admin::RunnersController#index as HTML
  Rendered layout layouts/admin.html.haml (Duration: 50.6ms | Allocations: 2137)
Completed 500 Internal Server Error in 99ms (ActiveRecord: 2.7ms | Elasticsearch: 0.0ms | Allocations: 9330)

ActionView::Template::Error ():
    1: - breadcrumb_title _('Runners')
    2: - page_title _('Runners')
    4: #js-admin-runners{ data: admin_runners_data_attributes }

Any idea how this could happen?
